To all whom itmm/ concern;

The invention for which this is an appli-- cation for Letters Patent,consists in improvements in internal combustion motors, driven byturbine action, in which the high temperature, produced by thecombustion of the gases, is lowered and kept at a sim lar temperature tothat' of the steam, by using steam, produced by the motor itself and thesame steam will be used as a power tor dr1ving'the turbine with thegases.

The primaryobject of my invention is to provide a turbine with one orseveral sets of rings of moving blades, and fixed blades, one next toanother; one or several combustion chambers secured to a plate withnozzles for the gases and for the steam; and two compressors, one forcompressing the air and the other for generating the gases. Thecompressors can be driven by the same or by different motors. p

The' same letters and numbers-in these specifications, apply to the sameletters andnumbers in the accompanying drawings.

The bevel gearH, is secured tothe pin J, to which is fixed the gear I, intermeshing with the gear K,secured to the drum L, which turns on the sleeve M. of the shaft C. Oneend of the sleeve M, is bolted to the plate N, and the opposite end iskept rigid by the braces 0,

which are bolted to the frame. On the drum L, is secured the cam wheel 1to this wheel are attached two cams Q and R, and two pins S and T. Thecam,Q on the circumference engages the rollers 1 of the lever V, and V;the cam R fixed on the plane side of the wheel P engages the levers U;the pin S, inserted on the side of'the wheel right below thecircumference engages the levers X; the pin T, which is longer andfarther from the circumference, engages the levers Y and Y.

Qt the two cranks of the crank shaft F one drives the pump for the aircompressor a, and the other drives the two pumps for the gas generator6. 'Theair compressor can be built by using some pattern already in themarket, provided thiswill .be of the capacity suitable for the motor.The compressor can compress the air in the explosion chamber directly oras it is done in the ac companying drawing, the air is compressed in theaccumulator c, and from the accumulator is discharged into the circulartube (Z, and from. the circular tube into pipes e, and from the pipesinto combustion chamber 7. The flow of the air is shut off from thecombustion chamber by the valve 9 operated by lever Y. The motor of theaccompanying drawing has five combustion chambers, and as the fivecombustion chambers are provided with the same valves and the samemachinery for their operation the description of one applies to theothers.

The other crank sets in action the double pump it, for generating thegas (Fig. 6). The piston it, in its outward movement sucks the airthrough the valve 7', at the same time that the piston 2', in itsoutward'movement sucks the oil through the valve Z. .On their return thepiston 2', willforce the oil through the valve m, into the chamber a,and the piston 7t, forces the air through the valve 0, and causes it toenter into the chamber a, at the same time as the oil; the air by mixingwith the oil will volatilize the oil, thus transforming the oil intogas. The continuing inward movement of the piston will increase thepressure of the gas in the chamber 12, the gas will force its waythrough, the valve 7), into accumulator 9 (Fig. 3) and from theaccumulator into the circular tube 1", and from this tube into the pipess, and from the pipes s, by opening the valves (7 operated by levers Y,will enter the combustion it Specification of LettersEatent.

At the point or unction ot the nozzle with the combustion chamber, whichis the hair-- roivestpart of the two, there is a casing tor the valve 7This valve in lowest part is composed @i' a flat solid piece of iietal 3Wide and. long enough to close the neck of the combustion chamberl)above the neck. the valve is perforated by circular hole to, of the samediameter as the opening that connects the combustion chamber with thenozzle. This valve is pivoted by the rod El, to tl e lever 3. 0n theother end of this lever is pivoted the rod il oi the pi to'n5. Thispiston works in the chamber 6, which opens into the interior of thecombustion chamber. At the moment the esp lo sion of the in thecombustion chamber, the pressure of the gases force the piston 5 up bycompressing the spring inverted on the rod t. By this'cpcraticn thelever 3 forces down. the circular open lg 10, of the valve y, and by sodoing opens the communication. between the combustion chamber and thenozzle. As soon as the gases have left the combustion chamber the spring7 forces the valve to its normal position.

The hole 8, which puts into communication the interior oi the combustionchamber with the atmosphere is opened and closed by a valve 8 operatedby the lever U (Fi This valve is opened mechanically by the engagementof the lever ll "With the cam propeiuv timed after the explosion topermit the scavenging of the vitiatec. gascs Simultanecusly withtheengagement ot the cam ll and the lever ll, segment Q, engages the roller1 of the lever Y to displace the lever V and open the valve 9 therebyadmitting air from pipe'e into the combustion chamber to effect thescavenging, the vitiate'd gases passing from the chamber through thevalve 8 as described. More detailed explanation of the operation. of thevalve g is had from the f llowing description. The compressed gases areadmitted by the vlavewhich is opened "y the lever V and closed by Y. The.f ls which enter into the construction of rose valves are the same forboth and their may of Working is the same also; so ll will describe oneand the description of this will e of ietal other hal' perforated byiolc ll. diameterof the hole is equal to that of pipe c. A stein isbolted below the sol part 10, which has a cas ng in form of a "l. llnthis casing insererl the upper part the lever l this lever has itsfulcrum on the pin'ld, and in its lower end carries the Wheel 1 which,when it str kes the segment ll, coinpels the upper end of the lever. andalso the valve, to swing from right to left. this operationcommunication is established between the interior of the pipe 6, and theinterior of the combustion chambe As soon. as the wheel leaves thespring l "forces the valve and its. lever to its normal position whichis to shut oil the communication ofthe combustion chamber Withthe pipe6.

By pushing the upper end of the lever toward the motorthetransverse bar 17, will be pulled back and will carry with it thelevers V-VY--Y, by so doing the valves will be disconnected and theresult Will be that the working oi the combustion chamber will bestopped. The Wheel P, continuing its run, will cause the pin S to strikethe lever Til; this will the segment (,3

The turbine B, is composed of a drum 2O,v

set in the frame composed of the plates 21- 22 and a tube 23, in Whichisinserted the shaft C and to this shaft is secured the turbine. On top ofthe drum are secured the moving blades 24. The turbine is covered by adouble casing; in the innercasing 25,

are secured the fixed blades 42. The moving 'nate rows, firstrow will bethe moving blades, the second row of 'fixed blades, etc. The innercasing will be as near as possible to the top of the moving blades andthe lower part of the fixed blades Will be as near as possible to thedrum. I

Each side of the drum terminates in two ribs 26-27. These ribs run inannular grooves in plates u and 28. The ribs should be made to fit inthe annular groove as perfectly as possible.

Theturbine is inclosed by the plates at and 28; the plate u separatesthe turbine from the box holding the combustion chambers and in thisplate are bored the nozzles 43 for the.combustion chamber and for the'steam 44. To these plates are bolted the casing 25 and the exteriorcasing 30, which, with the inner casing and the two side plates form theWater jacket 31 for the turbine. On the top of the water jacket issecured the steam chest 32, from which departs the steam pi e 33. Thissteam pipe passes through t e water. jacket of the combustion chamber,and is connected to the circular pipe 45, which is incased on the plateu.-

From this circular pipe depart the steam nozzles 44; the steam ejectedby these nozzles strikes the moving palettes of the turbine at the sameangle as the gases whichare ejected by the nozzles of the explosionchambers.

The water jackets 15 and 31 are in communication with each other throughopen-- ings 35 of the plate u. The Water is injected into the Waterjackets by the pump 36, through the pipe 37, and the condensed steamreturns to the condenser 38 through the pipe 39. The pump 41 is used tolubricate the different parts of the motor.

To start the motor, disconnect first the feeding valves 9 and 2, next,by some means turn the shaft C so as to start the pumps for the aircompressor and the gas generator, until the accumulators b and e, andthe 'tubular rings (Z and r, and the pipes e and s, are filled to theproper pressure with air .and gas. When the pressure is reached, openthe valves g and t of one combustion chamber, turn the shaft 0 againuntil the first explosion occurs, next open the valves of allcombustionchambers. To reduce the speed, shut off one or more combustion chambersfrom the feed. As soon as there is some steam accumulated in the steamchest (the water jacket will produce steam in a few minutes after themotor is started) open the steam valve by moving the lever 40 from rightto left. The steam in the turbine has .a double function; first, itprevents the heat produced by the explosions, from reaching a hightemperature in the turbine which would otherwise be red hot in aboutfifteen minutes and the consequence would be to put out of commissionthe motor; second, the steam adds power to the motor. To stop the motor,shut off all the feeding valves.

For the motor of which these are the specifications, any style ofturbine can be used according to the purpose to which it is to be put.

The motor above described has the advantage that no power is lost, asalmost all the heat energy is transformed into kinetic energy, and by sodoing it is possible to se cure a motorwhich is lighter than any othermotor, per H. P. which will develop. Another advantage is: that anindefinite number of motors can be operated with a single supply offeed.
